[...] The information I've had up to now is that KMS works well on x86 (if you have firmware installed) and fails on many PowerPC systems. I simply had no information about any other platform, and I tend to assume that if a feature is primarily used on x86 and is broken on another architecture that it is broken on more of them. But I think a lot of the problems with radeon on PowerPC are specific to the on-board Radeon chips in Mac systems which have odd firmware (no ATOM-BIOS). This presumably doesn't apply to any other architecture, and so only PowerPC should get the special treatment. Right?
